IMPROVEMENT IN GlMLET-VENTI'DUCTS.

Specification forming part of Letters Patent No. 131,4089 datedSeptember 17, 1872.

To all whom t may concern:

Be it known that I, J. F. PEACOCK, of Reno, Washoe county, State ofNevada, have invented an Improved Gimlet-Ventiduct; and I do herebydeclare the following description and accompanying drawing aresuiiicient to enable any person skilled in the art or science to whichit most nearly appertains to make and use my said invention orimprovement without further invention or experiment.

My invention relates to a device which I call a gimlet-ventiduct. Theobject of my invention is to provide a ready means of giving a vent tobarrels, casks, and other liquid-containing vessels. My ventiduct willalso answer for a sampling faucet.

In order to more fully illustrate and explain my invention, reference ishad to the accompanying drawing forming a part of this specification, inwhich- A represents the handle of an ordinary gimlet havingthe shank B.At the extremity of the shank is a gimlet or other pointed screw, O,whose base, where it joins the shank, is of smaller diameter than theshank, and the shoulder d thus formed is beveled inwardly, as shown. Ahole, c, passes diagonally through this screw, commencing at a pointnear the shoulder d and passing out at the side of the screw near thepoint, as shown. The screw is to be bored through a cork, if convenient,or it can be bored directly through the wood of the barrel, and whenturned down so as to bind the beveled or saucer-shaped shoulder dagainst the wood or cork a perfectly air-tight and water-tight joint isproduced, but when it is desired to give avent to the barrel, orsampleits contents, the screw can be turned backward until the outer openingof the vent-passage O is upon the outside of the barrel, while theopposite end communicates with the interior, thus allowing the ,passagethrough it of either air or liquid, as desired.

The combination of this vent-screw with the handle A and shank Bprovides a neat, convenient, and useful implement; but, if desired, thehandle could be dispensed with, and a square end be made upon the shank,as shown at Fig. 2, so that it could be turned by an ordinary wrench.

The faucet-ventiduct can be made of either wood or metal, and the screwC can be provided with any suitable style of screw-thread andpenetrating-point.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

The Ventilating-screw C provided with the vent-hole c, in combinationwith the shank B having an inwardly-beveled shoulder, substantially asand for the purpose above described.

In witness whereof I have hereunto set my hand and seal.
